♦ Check the hydraulic system reservoir to make certain that it is filled to the correct level with the proper
grade of oil.
♦ Make certain that the reservoir shut-off valve is OPEN.
♦ Check the hydraulic system for the correct pressure and flow.
♦ Check all winch and winch accessory gear housings for the correct oil level and grade. See Section 6.02
LUBRICATION.
♦ Engage the hydraulic pump drive and allow the oil to circulate and warm up for a few minutes before op-
erating the winch. This is particularly important during extremely cold weather.
♦ Check the operation of the drag brake.
♦ Check the truck body load area in a triangular section between the tail shelf sheave and both drum flanges
to see that there are no obstructions that could restrict the travel of the winch line or levelwind.
♦ Make sure the full load brake and drag brake have been bled to assure positive activation of the brakes.
See Section 3 for procedures.
IMPORTANT - BEFORE THE WINCH IS ACTUATED, THE FULL LOAD BRAKE MUST BE
BLED. See Section 3.05, INSTALLATION.
5. WINCH
OPERATION
The following procedures must be observed to assure safe and efficient winch operation:
♦ Refer to operating manual for the vehicle for specific operational instructions on the hydraulic system.
♦ Check the body load area to make certain there are no tools or equipment to restrict winch line travel or
level wind movement.
♦ Check the lay of the winch line on the drum and check for uneven build-up of the winch line.
♦ Check to be certain that the winch clutch is fully engaged, as described in Section 2, Precautions. With
rotation stopped, place the winch clutch control switch in the desired position for either paying out or
winding in.
♦ Operate the directional control valve to achieve the desired direction of drum rotation.
♦ Pull the load steadily and evenly.
♦ To stop the winch, release the directional control valve lever.
♦ When free spool is required, stop the drum rotation completely and disengage the clutch by moving the
control switch to the free-spool position.
♦ To control the drum speed in free spool use the caliper brake actuator lever and apply pressure according
to the amount of braking required to keep the drum from over-spooling.
CAUTION - THE DRAG BRAKE IS USED TO CONTROL THE DRUM SPEED ONLY. IT IS
NEVER TO BE USED TO HOLD THE LOAD.
♦ When finished using the winch, stow the free end of the winch line by passing the winch line through the
tail shelf sheave and hooking the pulling eye onto a fixed section of the chassis. A slight amount of ten-
sion should be maintained in the winch line to help prevent the formation of loose wraps on the drum.
6. MAINTENANCE
6.01 GENERAL - Inspection of the winch and related components should be a continuing procedure. The op-
erator should be constantly alert to detect clues to a potential problem such as unusual noises, excessive oil leakage
or overheating. The operator should report immediately any changes in the normal characteristics of the winch,
winch accessory or the hydraulic system.
